Add the module as dependency

Simply add the module as dependency to your main application module likes this:

angular.module("app", ["ng-webcam"]);

The directive

<ng-webcam 
    config="vm.config"
    on-error="vm.onError(err)"
    on-load="vm.onLoad()"
    on-live="vm.onLive()"
    on-capture-progress="vm.onCaptureProgress(src, progress)"
    on-capture-complete="vm.onCaptureComplete(src)">
</ng-webcam>
